This is mostly accurate.

Spark and Ark are unfairly conflated though.

Spark is a scam. Ark is well designed and when implemented properly, improves UX albit with trade-offs. New bitcoiners can recieve any amount of bitcoin in any number of transactions at zero cost, immediately, without the cost/friction of requiring a lightning channel. The main tradeoff is that VTXO's need to be refreshed periodically; however users could delegate this from their mobile/desktop wallet to any number of devices in their house etc. In the worse case, the Ark operator takes custody of your funds... so no worse than most other lightning wallets being used today.

Ark therefore has significant upside, but the downside is prettymuch the status quo.

Noah Wallet (Ark) is awesome - i use it most days to buy lunch... I scan a lightning invoice and one of my VTOX's is spent... trasaction time is 200ms-500ms. Early days, but I'm very confident that Ark will overtake Lightning in transaction volume and value.
